Ushuaia is the world’s southernmost city to capture the Southern Lights. It is also one of the easiest destinations to get to on this list as it has its own airport. Because it is so further south, the city is frequented with cloud covers and bad weather in general, making it a little difficult to view the lights. So keep a few days in hand, when you plan a trip to this spot. Also, head out of the city to someplace remote, to avoid any light pollution. While you are here, make sure to hit up the End of The World museum.
